METHOD OF CLEANING GAS-PRODUCER CONNECTIONS.

Specification of Lettersfatent. Application filed October 24.1905.Serial No. 284.226.

Patented Dec. 17, 1907.

To all whom it may concern:

Be it known that I, ROBERT H. MI LER, a citizen of the United States,and resident of St..Louis, Missouri, have invented certain new anduseful Improvements in Cleanilig- Out Methods for Gas-ProducerConnections,

I draft through said'stack.

. and efficiently remove the soot Y rior of the main. the main 1 is apipe 9 that'leads from a stuttions.

. tion partly in Heretofore it has been the practice to open themanholesinto gas producer, connections, and pass suitable tools through saidmanholes to remove the soot from said connec- But this method requiresmuch time and labor, and also allows air to pass into the interior ofthe connections, which results in a combustion of the soot that is beingremoved,

from said connections.

My improved method overcomes these objections, and stationary blowersare arranged which, when turned on, very quickly ducer connections. p Inthe drawings,- Figure l is a side elevasection of a gas main leadingfrom the producers, and showing my attachment connected thereto; Fig. 2is an enlar ed vertical section taken on the line 22 of Jig. 1;.Fig. 3is an lowout pipes. eferring by numerals to the accompanying drawings,1indicates the gas main that leads from the producer connection2, and ofa heavy sheet metal cylinder 3 that is lined with fire brick The end ofthis end that leads 4, or analogous material. main 1, opposite. from thefrom the producers, is lar connection 5 that discharges into a conduit6, that leads to and discharges into the stack.

Located at various points on the inain 1 are manholes 7 norma ly closedbydoors 8, by means of which access is had to the inte- Extending alongbeneath from the pro-' I enlar ed. section of the. vdlscharge end of oneof the% 40 provided with a tubu-' able source of steam supply. Connectedto .and extending upwardly from this pipe 9 at suitable distances. apartare short tubes 10,

I in which are located suitable cut-ofi valves 1 l Each pipe 10 isconnectedto-a cross union 12.,- that is located immediately beneath themain 1 and leading upwardly from-this union are three pipes'13 the endsof which are extended through thelower portion of the ma1n,and the endsof these three pi es within the main are curved toward the en thatdischar es into the stack; and said ends are flattened as indicated by14, to provide narrow discharge openings 15,

en it is desired to clean out the main 1, thefirst one of the valves thebody of the soot located in the end of the main 1 adjacent theconnection 2, and said soot is forcibly driven toward the opposite endof the pipe. The operator now successively opens the cut-off valves 11in the remaining pipes 10, and by so doing the soot is forcedto the endof the main that discharges into thestack by means ,of the'tubular con-'nection 5,- and thus all of the soot in the main is finallyblown intosaid stack from it is removed by the natural draft thereof.

' The-steam discharging from the flattened ends-of the pipes 13 suppliesthe volume which enables the stack to carry off the soot and likeproducts, whichsaid stack could not .do otherwise, as a vacuum! would becreated .unles'sthe' manholes were opened, or the producers kept under.pressure.

y improved apparatus for blowing out the main does away with thenecessity of opening the manholes in said main, and thus prevents thecombustion of the soot, and like products, and reduces the possibilityof the brick lining in the main from being heated to such a degree as toinjuriously affect the shell, by reason of the expansion and contractionof the brick.

be accomplished by openin series of cut-off valves, an thus much timesuitably formed apertures in 11 is opened, said first'valve, being theone nearest the producer whence C The blowing out operation canvery'ea'silya,

in sequence the and labor is saved, and the operation is completed muchmore eflectually than where suitable instruments are inserted throughthe manholesto remove the soot.

I claim: v

1. The herein described method of cleaning out" as producer connections,whichconsists in consecutively directing jets of fluid from-a series ofsets of jet pipes against the dust and other obstructions in saidconnec-' tions.

2. The herein described method of cleaning' out gasproducer connections,which con sistsv in consecutively directing jets of fluid from a seriesof sets of jet pipes against the dust-and other obstructions insaideonnec-' tions, thereby moving the dust-and obstructions step by steptoward a discharge opening, and then consecutively discontinuing the.flow of fluid from the jet'pipes as the obstructions are moved away fromthe same.

Inftestimony whereof, I have-signed my name to this specification, inpresence of two I M; P. smm, JOHN C. HIGDON
